High-precision self-scissor-type hydraulic lifting platform traveling mechanism

The utility model relates to a high-precision self-scissor-type hydraulic lifting platform traveling mechanism, and belongs to the field of hydraulic lifting mechanical equipment. On the basis of an existing scissor-type hydraulic lifting platform, an upper workbench is improved into a closed-loop three degree of freedom displacement control system, wherein the closed-loop three degree of freedom displacement control system is formed by taking an electro-hydraulic proportional valve as a control element, taking displacement sensors in three directions of transverse movement, longitudinal movement and rotation as feedback elements and taking a programmable controller as a controller. And then, +/-50mm of transverse movement and longitudinal movement for the table surface of a floating platform are realized, 0.25mm of micro-adjustment is carried out once, +/-10-degree of rotation is realized, 0.6-degree of micro-adjustment is carried out once, and the action is stable and reliable. The high-precision self-scissor-type hydraulic lifting platform traveling mechanism solves the defects of the scissor-type hydraulic lifting platform in the prior art that the platform working precision is insufficient and the working performance is low, so that the application occasion of the hydraulic lifting platform is wider.
